    • If you Build it, They will Come
Style: Work Light Pattern Name: 350 Lumens Size: 1 Pack
Update June 5th 2018, have used extensively since Jan 24 2017 and up'd from 4-5 stars, still holds charge for at least 4+ hours, probably longer, I use it extensively for auto repair, that led cover is constantly banging against engine components with no worry. I stand it on its base on my garage floor and have knocked it over countless times right on led cover, no issues. Last light you will ever own, Id never buy a "flashlight" again. I initially complained it didn't seem so bright on my engine in daytime, dumb complaint and removed it , this may be best auto light out there as Its thin and I can weave it into tight spots in engine bay. This really is an incredibly well made product, you don't see that very often today as nearly all mfg's are priced concerned much more than quality concerned, however this is an an example of " If you build it they will come". Brightness. Wow! My first test was up in my master bedroom at night. I stood near one corner point this away from me, Its 27x35 with 16 foot ceilings, this lit it up completely and lit up the 16x18 bathroom through its open door as well. I pointed it up to the ceiling and it light the room up well. Extensively used for auto work on 4 cars, It lights up the engine well and I dont have to worry about shattering glass going into my intake manifolds, certainly puts out alot of bright light unlike my 6 inch reflective enclosure and way hot bulb you cant take that under the car and hang it in tough places, like I could with this light. The led's are also high quality, you may find a brighter light but you won't get the time of operation due to cheap LED's sucking major power, these are not cheap led's, super bright and stays COOL. Manufacture Quality. Gets an A+ I'm a hardware engineer, this is high quality. The on/off rocker switch is at the bottom if you look at the picture show when its standing up on its own. A super high quality rocker switch that will easily last your life time, I know because I spec this same style in products I design. Rather than going "disco" and putting a USB style charge connector on it, it has a heavy duty barrel type interface made of hard steel with a nut securing it to the base. A USB interface would be a poor choice despite the marketing appeal of using "USB" but as far as life time and reliability and ability to carry a large charging current USB falls far short, a sturdy barrel type connector is entirely the proper choice here. The handle is covered with heavy duty "rubber" for lack of a proper name for the material, very thick, has ridges for grip and 2 - 6 point socket style molded ridges , one near the bottom by power interface and power switch and one near where the leds starts to keep it from rolling when you lace it down. The leds are to bright to look at and its great that half the led length tube is blocked out so light only goes one way otherwise you'd be blinded. It may have been better to make that inner surface silver reflective, but I doubt it matters much. I haven't dropped it yet but it seems the most critical component which is the clear cover over the leds seems pretty solid and not a very brittle like material which would easily fracture. Accessories. The top hook will swivel 360 degrees but you should grab it down where it actually connects to the top of the light, the 360 swivel is tight which is good so it doesn't move on you but if you try to rotate it 360 by holding onto the hook you will probably eventually warp or break the top hook. The top hook also can rotate and fold down along the body if you want it out of the way and that rotational directing is very easy. The hook itself has flex in it which is good, you don't want stiff plastic that will brittle fracture. The second hook clips on the handles any where you want it to and I found this great to hang the light horizontally as I had freedom to place that 2nd hook to exact position needed. The magnet is same type of clip where you like it, its very strong, no worry about it not holding to metal like many other cheap magnetic hold products I've seen. Only thing is you cant clip it such that you can make the light stand up, the magnet will always be 90 degrees to the light. The charger has red led when charging , green when done, you will see an label "LED1" on a horizontal led at bottom of led tube near the handle, this comes on when your charge gets low, some other reviewer said he wished it had a warning feature and this is it. Other Stuff: Some ask if it will get "dim" as battery discharges. No it won't, led's do not work that way, they are basically on or off when proper minimum voltage is present. Warning. Do not try to charge this with other barrel type chargers, this charger has a low voltage about 4.4 v and it needs to be what ever it says on the charger to avoid your battery blowing up. One question asked was " Can you replace the batteries". This is not made to easily replace the batteries that are used internally. But to me, it seems like the rubber handle that makes up the bottom half of this light was slid on to probably a plastic frame during manufacturing.MY guess is you can slide this off, of course that will be very hard. Best thing would be to heat it up slowly so it becomes more flexible then work it off, maybe spray some WD-40 down the slides as it becomes flexible. You can also just cut it and band-it back together. But I suspect it doesn't matter, this will probably last a long time and you will more than get you money's worth. Mad Scientist Engineer's like me do this type of thing. Definitely buy, don't try to save 10$ on a cheaper unit, this is the real deal. ... show more

    • Excellent light
Style: Work Light, UV Pattern Name: 1,000 Lumens Size: 1 Pack
Bought this for work where i need a wide cast of UV light, and also at times a regular working light for dim rooms. The battery life is awesome, I use it every day for about 15 minutes at a time and I charge it maybe every other week. I have also had jobs where I needed standard working light for about 6 hours and it stayed on the entire time and still had some battery life left. The UV throw is wide and powerful. I refinish bathtubs and the primer I use has UV ink so you can see if you missed any spots and this light makes the entire bathtub light up completely. I do use it in the dark which helps the UV a lot but you can also use this in daylight up to about 2 feet away and still see UV dye shine. The magnets are strong enough that it holds it's own weight even vertically, but if you bump into it it will likely fall down. The hooks are also nice for me specifically, I can hook it onto the shower rod and light up the tub for hands free work. OVERALL amazing work light. Highly recommended ... show more

    • Bright and versetile
Style: Work Light Pattern Name: 1,000 Lumens Size: 1 Pack
I'm just a home mechanic but do more than average repair tasks and love this light! I use it mostly in high and most recently used it to replace the lift pump on an older Dodge diesel. It ran for 6 hrs straight! Magnet is strong enough to hold it in any position and the light output is amazing! Lightweight too... It's my go-to light for all my repair work now. I do turn it off when I know I'm going to be away for a few minutes, and also plug it in to recharge as much as possible... After all, it is battery powered! Overall a really good light! Much better than the old incandescent or flourescent that always needed an extension cord... As far as I'm concerned, those days are long gone! I'd buy another in a heartbeat! Update 4 years later: light is still amazing and I’ve used it pretty regularly and hard! But what I’ve noticed is that it seems like the battery is reaching the end of its practical lifespan. It comes on at full brightness but tends to shut itself off after about 30 minutes use. It turns back on without issue, but continues to shut itself off after a short time. And the battery is not replaceable. That being said, this light served me very well and a 4 year battery lifespan isn’t bad in my book for something I’ve used so much. I will definitely be purchasing another in the not too distant future! :-) ... show more

This is a decent light and it works well. My only complaint is the battery life is only a couple hours. I end up buying two so I could have one charging as using the other one
